White Space Usage for Wireless Local Area Network Devices

1. A method, said method comprising: receiving a beacon message, said beacon message having a clock descriptor field, a master clock descriptor field and a quiet period scheduling field; inspecting said clock descriptors field and said master clock descriptor field in said beacon message; selecting a master clock responsive to said inspection; and transmitting a message to schedule a quiet period based on said selected master clock, wherein said master clock is selected based on one of stability, accuracy and speed.

2. The method according to claim 1 , wherein said method operates in an access point.

3. The method according to claim 1 , wherein said selection is performed by executing IEEE 1588 master clock selection method.

4. The method according to claim 1 , wherein recipients of said transmitted message modify a time stamp in said messages responsive to time to receive and process said messages.

5. An apparatus comprising: means for receiving a beacon message, said beacon message having a clock descriptor field, a master clock descriptor field and a quiet period scheduling field; means for inspecting said clock descriptors field and said master clock descriptor field in said beacon message; means for selecting a master clock responsive to said inspection; and means for transmitting a message to schedule a quiet period based on said selected master clock, wherein said master clock is selected based on one of stability, accuracy and speed.

6. The apparatus according to claim 5 , wherein said apparatus is an access point.

7. The apparatus according to claim 5 , wherein said means for selection is performed by executing IEEE 1588 master clock selection method.

8. The apparatus according to claim 5 , wherein recipients of said transmitted message modify a time stamp in said messages responsive to time to receive and process said messages.

9. An apparatus comprising: a transceiver, said transceiver receiving a beacon message, said beacon message having a clock descriptor field, a master clock descriptor field and a quiet period scheduling field; control logic, said control logic inspecting said clock descriptors field and said master clock descriptor field in said beacon message, said control logic in communication with said transceiver; said control logic selecting a master clock responsive to said inspection; and said transceiver transmitting a message to schedule a quiet period based on said selected master clock, wherein said master clock is selected based on one of stability, accuracy and speed.

10. The apparatus according to claim 9 , wherein said apparatus is an access point.

11. The apparatus according to claim 9 , wherein said control logic selects said master clock by executing IEEE 1588 master clock selection method.

12. The apparatus according to claim 9 , wherein recipients of said transmitted message modify a time stamp in said messages responsive to time to receive and process said messages.
